Roller chain coupling consists of a common chain ,two side by side sprockets which have the same number of teeth and a cover.There are following types of roller chain coupling:double roller chain coupling,single roller chain coupling,toothed chain coupling,nylon chain coupling,etc.Double roller chain coupling structure is superior to other types of couplings and widely used.

Features of roller chain coupling:

1.Simple structure,easy essembly and disessembly.

2.Light weight,and long service life

3.Have a certain ability to compensate for installation less precision
